John shares his personal experience with Jesus to remind the churches about the truth of the real, physical Jesus Christ, whom he personally encountered, walked with, talked with, and saw after His resurrection, before he experienced the inaugural effect of the Holy Spirit himself, as well as the other disciples, 40 days after Christ's resurrection. That said, John's message is very deep, spirit filled, and loaded with energy. In this portion of his letter to the churches, John encourages fellowship with one another. He confronts false doctrine (in the form of what is known as the Gnostic gospels-completely taking away the godly qualities of Jesus Christ). And in this portion, John exhorts believers to walk in the light of Christ and to, in that light, walk with each other.
